Definitions

  • the invention relates to a wire mesh band for an apparatus wherein the band travels in the direction of its warp wires over rotatable rollers, with wires extending transversely to the direction of travel of the band which exhibit protrusions extending beyond the underside of the fabric which engage into guide grooves on the circumference of the rollers.
  • Wire mesh bands of this type are used as conveyor belts for various goods in industry, particularly where hot goods or goods requiring drying have to be conveyed. These goods are also sometimes required to come into contact with air from beneath and therefore require a permeable support. Wire mesh bands are also suitable for use as support bands for travelling filter surfaces, or in double arrangement as a retaining device for substances which are required to be passed continuously through a treatment liquid.
  • a wire mesh band of the type initially explained is described in U.S. Pat. No. 3,368,663 wherein all the weft wires of the fabric have "V" shaped protrusions arranged at an interval of twice the warp pitch, which engage peripheral grooves of rollers so that the wire mesh band traveling over the rollers is guided laterally.
  • Such wire mesh bands can only be constructed as wide-mesh fabrics in which the width of the meshes across the band is considerably greater than their length in the direction of travel of the band. Furthermore, a very large number of rows of protrusions distributed across the width of the band are obtained, for which a correspondingly large number of peripheral grooves must be provided in all the driving, supporting and return rollers of the apparatus over which the wire mesh band travels. The production of such grooves in the rollers involves substantial costs.
  • the wires provided with protrusions are substantially rectilinear guide wires provided with at least one flattened part oriented in the weft direction and woven in at an interval of several meshes, which exhibit at least on protrusion bent beyond the underside of the fabric.
  • This configuration has the advantage that guidance of the band is possible not only with wide mesh fabrics, but pratically for any desired wire mesh, because the protrusions are provided, not in the regular weft wires, but in special guide wires which can be woven into any fabric including fabrics with square meshes or various other weave patterns.
  • the proposed flattened part prevents the guide wires from rotating about their longitudinal axis in service. The protrusions of the guide wires therefore always stand perpendicularly to the plane of the mesh band.
  • the width of the guide wires is conveniently greater than the width or the diameter of the weft wires of the fabric.
  • the width of the guide wires may be equal to the interval of the weft wires in the fabric. An extremely firm binding of the guide wires is achieved by this means.
  • the guide wires are conveniently of half-round or half-oval cross-section. Their half-round or half-oval surface is located on the underside of the fabric confronting the rollers, beyond which the protrusions project.
  • the protrusions With this cross-sectional shape of the guide wires, the protrusions have a domed or rounded surface in the direction of travel of the wire fabric band, so that they run into the peripheral grooves of the rollers particularly easily and thereby guide the band particularly well.
  • the guide wires may also have a rectangular cross-section and be rounded at their edges. Substantially the same effect as with half-oval cross-sections is achieved by this measure.
  • individual weft wires of the fabric may be replaced by woven-in guide wires with protrusions which then extend continuously across the total width of the wire fabric band and thereby not only assume the lateral guidance of the wire fabric band, but also simultaneously effectively stiffen the band in its transverse direction.
  • the length of the guide wires may be shorter than the width of the wire fabric band.
  • wire mesh band In the case of very wide wire fabric bands it may be convenient to arrange a plurality of short guide wire sections in a row in the transverse direction of the band so that the protrusions of each guide wire section align with the protrusions of the guide wire sections woven-in longitudinally behind them.
  • the wire mesh band then has a plurality of rows of guide wire sections with one or more protrusions spaced along the band longitudinally.
  • the bent protrusions in the guide wires or guide wire sections are conveniently "V" shaped, and their base width conveniently corresponds to a multiple of the warp pitch.
  • a warp wire comes to lie in each case in the nip in which an arm of the "V" shaped protrusion bends out from the rectilinear part of the guide wire or of the guide wire section.
  • the warp wires which lie in the region of the protrusions run continuously in the fabric, so that the fabric surface is not interrupted at the bends of the guide wires. This is important for sieve netting bands and other applications which must not exhibit large holes at individual points as is the case with the known wide-mesh fabrics.
  • the guide wires with the protrusions may consist of brass or steel, whereas the wire mesh is woven entirely or partially from plstics wires.
  • the guide wires may also be convenient in individual cases to produce the guide wires with the protrusions from a different material than the wires of the wire mesh band.
  • the guide wires may consist of brass or steel, whereas the wire mesh is woven entirely or partially from plstics wires.
  • FIG. 1 shows a detail of a wire mesh band according to the invention in plan
  • FIG. 2 shows the wire mesh band according to FIG. 1 in a cross-section made along the line 2--2 with a partial view of a support or return roller over which the wire mesh band travels;
  • FIG. 3 shows a second embodiment of the wire mesh band according to the invention in a partial plan view similar to FIG. 1;
  • FIG. 4 shows the wire mesh band according to FIG. 3 in a cross-section made along the line 4--4 with a driving or return roller in elevation, upon which the wire mesh band rests,
  • FIG. 5 shows one of the guide wire sections used in the wire mesh band according to FIGS. 3 and 4 in a perspective view and on a considerably larger scale
  • FIGS. 6 to 8 show various cross-sectional shapes for the guide wires used according to the invention.
  • 10 designates a wire mesh band for a conveyor apparatus.
  • the wire mesh band is constituted by a customary square mesh fabric, the comparatively thin and flexible warp wires 12 of which are woven with somewhat more rigid weft wires 14 extending transversely to the direction of travel 13 of the band 10.
  • each guide wire 15 has five protrusions 18 (FIG. 2) arranged at lateral intervals and bent-out beyond the underside 17' of the fabric 10; said protrusions 18 engage into peripheral grooves 19 of the support or return roller 11 when the band 10 travels over said roller 11. If the band 10 has a tendency to wander sideways, i.e., to deviate from its straight direction of travel 13, it is repeatedly straightened in the region of the roller 11 because the protrusions 18 slip with their flanks 20 on the respective edges of the peripheral grooves 19 and into the latter.
  • the guide wires 15 cannot rotate about their longitudinal axis, they have on their surface a flattened part 21, which need not absolutely be completely plane, but may also be slightly curved.
  • the guide wires may have the cross-section of a flat oval illustrated in FIG. 8.
  • the width B of the guide wires 15 is greater than the diameter D of the weft wires 14 of the fabric so that the wire fabric 10 is considerably stiffened in the weft direction 16 by the guide wires 15.
  • a plurality of short guide wire sections 22 and 23 are disposed in a row at a longitudinal interval "e" along the transverse or weft direction 16 of the band 10.
  • guide wire section 22 with two protrusions 18 are present in the regions of the lateral edges 24 and 25 of the wire mesh band 10, and a short guide wire section 23 in the center of the wire mesh band 10.
  • the transverse groups of guide wire sections 22 and 23 have a lateral or warp interval in each case of three meshes 17, and that the protrusions of all the guide wire sections 22 and 23 align in the warp direction.
  • the guide wire sections 22 and 23 have a width B which is equal to the interval "f" between two adjacent weft wires 14.
  • the guide wire sections 22 and 23 are woven into the wire mesh fabric 10. They do not take the place of a weft wire 14, but lie between the latter.
  • the base width "g" of the protrusions 18 is dimensioned so that it corresponds to twice the warp pitch 26, that is, the mutual interval of the warp threads. Due to this, a warp wire 12 comes to lie in each case in the nips 27 which the "V" shaped protrusion 18 forms with the straight parts 28 of the guide wire sections 22 and 23. Consequently, the guide wire sections 22 and 23 cannot be displaced in the transverse direction 16 of the wire mesh band, in which they are tightly bonded.
  • the guide wire sections 22 and 23 have a half-oval cross-section.
  • the plane surface 21 is placed upwards in the wire mesh section, whereas its half-oval face 29 is located on the underside 17' confronting the roller 11.
  • the protrusions 18 are therefore also bent outwards towards this oval surface 29 (FIG. 5).
  • the guide wire sections may also have the half-round cross-section illustrated in FIG. 7 or the rectangular cross-section shown in FIG. 6.
  • the guide wires with rectangular cross-section are conveniently rounded at their edges.
